MARY BACON MARTIN, OF NEYV YORK N. Y.

PROCESS OF STAINING PAPER,I&.0.

SPECIFICATION forming part of Letters Patent No. 321,234, dated June 30, 1885,

Application filed December 10, 1884.

To all whom it may concern:

Be it known that I, MARY BACON MARTIN, of the city, county, and State of New York, have made an invention of certain new and useful Improvements in the Process of Staining Paper and other Materials, and of a new article of'manufacture produced thereby; and I do hereby declare that the following is a full, clear, and exact description and specification of the same.

The object of this invention is to produce upon paper and other suitable materials a clouded colored surface, with or without the aid of bronze, and the process and products thereof are specified in the claims at the close of this specification.

In order that the same may be fully understood, I will proceed to describe the best mode in which I have thus far practiced my process.

The colors which are used by me are what are commonly known as water-colors, and consist of pigments mixed with water (with or without sizing) to such tint as may be found expedient. The color chosen is applied in a wash to the paper to be stained, the application being made by means of a brush or by means of a roller whose surface is formed of bristles or hairs, so that it is in substance a roller-brush. Immediately after the color is applied a roller covered with blotting-paper, so as to form an absorbent, is run over the washed surface, the practical efiect of which is to absorb the surplus color and to leave the residue irregularly distributed, so that the paper has a clouded colored surface. The absorbing roller also partially dries the paper, so that it is left in a damp condition. The paper is permitted to dry, and, if desired, is flattened by a slight pressure during drying.

If desired, two or more washes of colors differing from each other may be applied in succession to the paper, the application of each wash being succeeded by the absorption of the surplusby means of the absorbingroller or its substitute for that purpose.

If the paper is to be bronzed as well as colored by the above-described process of washing and succeeding absorption, the bronze should be applied either in a liquid or in a dry powdered condition to the paper before the application of the color, or before the application at least of the last coat of color, and

(N0 sp ecimens.)

the succeeding coat or coats of color should have ox-gall or some substitute therefor mixed with it in order to insure the proper covering of the bronzed surface before the absorbing operation is effected.

The sheets which have been colored by means ofpigments mixed with water without ox-gall or sizing may have the colors fixed, without glazing, by the application of one of the well-known fixatives-such, for example, as the charcoal. fixative used for fixing crayon-drawings.

If deemed best, the color and bronze may be applied simultaneously to the paper, or the bronze may be applied after all the coloring, and may be fixed to the paper or other material by a sizing or other fixative. The surplus color also may be absorbed by means of blotting-paper in the sheet or in the form of a pad instead of by a blotting-roller.

The paper which I have used with success is Whatmans rough drawing-paper; but the invention is not restricted to the use of paper, as leather-such as that used in wall decoration-Morocco leather, and book-binders cloth may be colored, or colored and bronzed, by thev abovedescribed process in the same manner as paper, the coloring being effected either before or after the material is sized, as deemed best. The process also is not restricted to water-colors or to flexible materials. Thus, plastered walls may be colored by the same process with oil-colors. In this case the oil-colors are thinned with spirits of turpentine and applied to the wall with a brush, and the surplus is subsequently absorbed by running a blotting-paper roller over the colored surface.

The practical effect of the above-described process is the production of a clouded colored surface entirely distinct from the effects produced by the process commonly called marbling, and the material produced is highly useful for decorative purposes, and may be used for decorating the walls of rooms, for book-binding, for covering paper-boxes, and for other purposes to which it is applicable.

I claim as my invention- 1. The process, substantially as before set forth, of coloring material by the application thereto of awash of color, and by subsequently absorbing the surplus color, substantially as before set forth.

2. The process, substantially as before set 4. Asanew article of manufacture,abronzed forth, of coloring and bronzing material by material colored with awash of color, the surthe application thereto of a wash of color, by plus of which has been removed by absorpabsorbing the surplus thereof, and by the aption, substantially as before set forth.

5 plication to the material of bronze, all sub- In witness whereof I have hereto set my I 5 stantially as above set forth. hand this 4th day of December, A. D. 1884.

3. As a new article of manufacture, mate- MARY BACON MARTIN. rial colored with a wash of color, the surplus Witnesses: of which .has been removed by absorption, WILLIAM J. KELLY,

FRED INGRAHAM.

10 substantially as before set forth.
